TSM uses alias names to identify tape and optical disk devices to the TSM device driver. Device names for the TSM device driver differ from device names for the Windows device driver. For example, an automated library device might be known as LB0.0.0.1 to the TSM device driver and as LIB01 to the Windows device driver.
Administrators using the Device Configuration Wizard to initially configure devices need not be concerned with device alias names because the wizard automatically provides the device name in the form TSM requires. However, administrators configuring devices using TSM commands must provide the device names as parameters to the DEFINE DRIVE command. Administrators modifying device driver control may need to provide alias name information in the Device Exclude List. The names can be either:
Alias names identify TSM devices and are required when configuring devices using TSM commands. Alias names replace the real device names in TSM commands and screens. The TSM device driver communicates with devices by using the alias names. See "Obtaining Alias Names for Devices".
Alias names appear in the form mtx.y.z.n or lbx.y.z.n or opx.y.z.n, where:
mt3 (Tape drive at SCSI ID 3, LUN 0, bus 0, port 0)
mt5.0.0.1 (Tape drive at SCSI ID 5, LUN 0, bus 0, port 1)
lb4.1 (Library at SCSI ID 4, LUN 1, bus 0, port 0)
op4 (Optical drive at SCSI ID 4, LUN 0, bus 0, port 0)
